Storm damage and atmospheric debris is one of the main reasons for roof leaks and damage to the interior of buildings, costing building owners thousands, if not millions of dollars over the lifespan of a roof system. Ensuring your building is watertight at any time is critical while weather continues to wear down details. Thanks to years of accumulated data, we know there are evident patterns when it comes to the weather in Sydney, New South Wales. This allows us to know what to expect and plan ahead for those inevitable seasons and months. This is incredibly important information, especially for homeowners and property owners/managers; knowing which months will have the highest amount of rainfall/hail and strongest winds during the year can allow you to prepare your roof, protect your assets and plan your budget. How much does it rain in Sydney, and what Months have the most rainfall? In Sydney, during the entire year, the rain falls for 143.4 days and collects up to 1212.1mm of precipitation. Looking at the graph below, we can see that March through June is the period with the highest amount of rain throughout the year, with March accumulating 129.2mm. However, June is the month with the most rainfall in Sydney, Australia. Rain falls for 12.5 days and accumulates 131.9mm of precipitation. [1] What is the windiest month in Sydney? Averaging at 13.8 km/h (8.6 mph), November is the windiest month, whilst March is the calmest at 11.3 km/h (7.0 mph). [2] Clients are often surprised to realise their roof area can be quickly covered in debris and require further cleaning shortly after completing roof washing. As the main protecting layer for your building against all elements, it can quickly collect damaging matter. It is important to notice when wind has recently been high; although you may not see it – a build of debris could be occurring causing blockage in gutters and drains leading to major drainage issues such as heavy ponding, that otherwise could have been avoided. High winds can also cause roof components to blow off or become loose leading to future leak areas from caused damage. There also can be cases where mechanical/electrical equipment becomes loose and blows around the roof causing damage leading to a leak. What is the month that hail occurs the most in Sydney? Hailstorms occur most frequently between October and February (spring and summer) in NSW, with peak activity in November and December. The hail season in Sydney begins 2 months earlier (August to February). However, during the last 14 years there has been a shift to November to March. [3] For metal roofs – if not taken care of immediately - hail can cause dents in the sheets and chip away at the top layer of paint, causing the life of your metal roof sheets and flashings to end prematurely. Early corrosion can occur in significant dents if ponding occurs, this can cause the paint to fracture and leads to structural weak points within the sheets. However, metal roofs don't suffer as much as tile roofs. In recent hailstorms, tile roofs have been damaged the most and needed more repairs, this further adds value to why metal roofs are better. What are notable events we have experienced so far this year? Between 7 and 9 February 2020, the Sydney metropolitan area received its heaviest rain in 30 years due to an east coast low (which is unusual in the summer). The storm brought vast flooding and strong winds that caused commuter chaos and left over 20,000 homes without power.[4] The city recorded around 391.6 mm of rain within those three days, more than three times the average rainfall for February. Thousands of people living in depressed areas, such as those in Narrabeen and southwest of Sydney near Georges River, were told to evacuate due to billowing floodwaters and rising river levels. At least 200 people were rescued by emergency services during the stormy weekend. Warragamba Dam, which was only at 42% in capacity, reached as close to 70% after the deluge.[5][6] The last time more than 300 mm of rain fell in two days in the city was in 1992, in addition to being the wettest four-day period since 1990.[7] In the late evening of 18 February 2020, over 60,000 lightning strikes hit the Sydney area,[8] with wind gust over 100 km/h being recorded in some Sydney suburbs. The storm toppled trees, damaged properties and left tens of thousands of homes without power.[9] What do we know and where to we go from here?
